CHURN.

I No. 824,164.

Specification of Letters Patent.

Patented June 26, 1906.

To all whom it may concern.-

Be it known that I, J HN W. WILLsoN a,

citizen of the United States, residing in Granite City, in-the county ofMadison and State of Illinois, have invented certain new and usefulImprovements in Ohurns, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this specification.

My invention relates to churns; and it has particular reference to anovel form of agitator whereby cream may be more quickly and efficientlychurned to produce butter than is possible in the use of many of thechurns heretofore used.

My invention has further reference to the gearing by which thechurn-dasher is operated and a gearing-supporting frame, includingadjustable members, whereby members of the gearing may be shifted tosecure the desired tension upon other of the gearing members.

Fi ure I is a to or plan view of my churn. Fig. I is a side e evation ofthe churn. Fig III is a view, partly in vertical section and partly inelevati0n,.illustrating the churnagitator and the gearing members mostnearly associated therewith. Fig. IV is a perspective view of the frameof my churn.

1 designates an agitator, which is of conical form and the widened orbase portion of which is at its bottom. The surface of this agitator ispreferably smooth and free of projections. erated in a vessel orreceptacle of any ordinary description, such as a tub A. (See Fig. II.)The agitator 1 is provided witha shank 2, which is rotatably supportedin a frame, to be hereinafter described, and to which power is appliedfor the purpose of imparting rotation to the agitator. The agitator isdesigned to be rotated in a vertical position, and due to its peculiarshape it opcrates during the churning action within the vessel A toconstantly agitate the cream present in'said vessel with a swirlingmotion, during which action the cream is projected upwardly in thevessel, due to the agitator being wider at its. base than at any pointabove its base.

3 designates the forward legs of the gearing-supporting frame of mychurn, and 4 represents the rear legs. The forward and This agitator isdesigned to be oprear legs are united by two pairs of side bars 5,spaced apart from each other and secured to the upper ends of said legs.

6 is a tie-bar connecting the two rear legs 4, to which it ispermanently fastened.

7 designates a pair of front cross-bars adjustably .fitted to the sidebars 5, one of said cross bars being located beneath the forward ends ofthe side bars and the other cross-bar being located above the forward'ends of the side bars. The cross-bars are secured to the side bars foradjustment by clamping-bolts 8, that pass vertically through thecross-bars and through the spaces between the pairs of side bars. Itwill be seen that by this construction the forward crossbars may beshifted forwardly or rearwardly relative to the side bars 5 to obtainany desired degree of adjustment.

bars 7 and to which power is communicated in a manner to be hereinafterdefined.

-12 designatesa pair of vertically-adjustable cross-bars un1t1ng theupper ends of the rear I Each of the forward 1 cross-bars is providedwith a vertical opening 7 9, in which the shank2 of the agitator 1 isrotalegs 4, which extend above the main portions of the frame and areprovided with vertical slots 13. .The cross-bars 12 are spaced apart sothat they embrace the upper ends of the legs 4, and they are upheld inadjusted position by clamp-bolts 14, which pass horizontally through thebars adjacent to their ends and through the slots 13. In eachverticallyadjustable cross-bar is an aperture 15, said apertures beingpreferably produced by recessing the cross-bars and applying to themrecessed cleats 16.

17 designates a pair of horizontally-adjustable central cross-bars thatare movably fitted to the side bars 5 in positions corresponding tothose occupied by the forward cross bars 7. These .central cross-barshave their ends fitted to the side bars 5 above and below said sidebars, and they are adjustably held to the side bars by clamping-bolts18, which pass through the central cross-bars and through the spacesbetween the side bars. In

the center of each central cross-bar is a bearing-opening 19.

20 designates a pair of pulleys supported in vertical positions by thetie-bar 6, that connects the rear legs of the churn-frame.

21 designates a main drive-pulley, the shaft of which is mounted in theopenings of the vertically-adjustable cross-bars 12 and has appliedthereto a crank 23.

24 is a horizontal driven pulley that is located between the centralcross-bars 17 and is provided with a vertical shaft 25, that operates inthe openings 19 in said cross-bars. The pulley 24 has rigidly'fixedthereto an auxiliary pulley 26, preferably of larger diameter than saiddriven pulley 24.

27 designates a belt that operates upon the eriphery of the drive-pulley21, (said pulley being preferably grooved for the reception of thebelt,) this belt passing from the drive-pulley to. and under one of thepulleys 20 and therefrom to the driven pulley 24, from which it returnsto the other pulley 20 and to the drive-pulley 2,1. It will be seen thatupon rotation being imparted to the drive-pulley through the medium ofthe crank 23 power is transmitted from said drive-pulley through thebelt 27 to. drive the driven pulley 24 and also the auxiliary pulley 26.

28 is a belt that is fitted to the periphery of the auxiliary drivenpulley 26 (said pulley beingpreferably grooved for the reception of saidbelt) and which extends from said pulley to the pulley 11, fixed to theshank of the agitator 1. This last-named belt serves to trans mit powerfrom the auxiliary driven pulley to the agitator-p.ulley, which latterpulley being of smaller diameter than the pulley from which power istransmitted has power applied thereto in a manner to produce a highspeed of rotation of the pulley by which the agitator is driven, therebycausing the agitator to be very rapidly rotated inv the vessel in whichit operates.

I claim 1. In a churn, the combination of supporting-legs, side barssupported by said legs, an agitator-supporting bar adjustably secured tosaid side bars, means for holding said bar in adjusted positions, anagitator supported by said adjustable bar, and gearing for driving saidagitator, substantially as set forth.

2. In a churn, the combination of supporting-legs, horizontal side barssupported by said legs, forward horizontal cross-bars adjustably securedto said side bars, an agitator rotatably mounted in said cross-bars,rear horizontal cross-bars adjustably secured to said side bars, apulley journaled in said rear cross-bars, a belt leading from saidpulley to said agitator, and means for driving said pulley,substantially as set forth.

3. In a churn, the combination of supporting-legs, horizontal side barssupported by said legs, forward horizontal cross-bars adjustably securedto said side bars, an agitator rotatably mounted in said cross-bars,rear horizontal cross-bars adjustably secured to said side bars, apulley journaled in said rear cross-bars, a belt leading from saidpulley to said agitator, a second pulley fixed to said first-namedpulley, vertically-adjustable bars secured to a pair of said posts, apulley journaled in said last-named bars, and, a belt connecting the twolast-named pulleys, substantially as set forth.
